The lines on absorption atomic spectra correspond to energies needed for electrons to be excited from a lower energy level to a higher energy level. assume that the energy needed for an electron in 2p orbital in an o atom to jump to 3s orbital is 3.6*10^-19 j, what is its wavelength of the line atomic spectra in nanometer (nm)?
note: use whole numbers and 3 sig figs, or no decimal place.

553 nm

Explanation:

When an electron from O absorbs radiation with an energy (E) of 3.6 × 10⁻¹⁹ J, it is excited from orbital 2p to orbital 3s. The wavelength (λ) associated with that radiation can be calculated using the Planck-Einstein equation.

E = h. ν = h . c . λ⁻¹

where,

h is the Planck's constant

c is the speed of light

ν is the frequency

the answer for sodium is 0.186

the answer for rubidium is 0.251

the answer would be b i believe
